Title:
  OVS flow rules should strip vlan for tunnel data

Status in OpenStack Neutron (virtual network service):
  Invalid
Status in neutron grizzly series:
  In Progress

Bug description:
  GRE tunnel payloads in grizzly contain the local VLAN tag used on the
  sending side's integration bridge. This serves no purpose, wastes
  bandwidth, exacerbates MTU issues, and slows processing in the kernel.
  It can easily be addressed by adding a strip_vlan action to the
  set_tunnel flow rule.

  Note that the flow rules have changed substantially in havana, and
  include the strip_vlan action. Grizzly needs its own fix rather than a
  back-port from havana.
